The development of teaching and learning materials is an essential component of endangered language revitalisation, yet there is very little academic research on this crucial topic. Our volume seeks to address this imbalance by examining endangered language pedagogical materials from around the world including traditional resources such as grammars, dictionaries, and textbooks, as well as new media such as online courses, apps, video games, etc. Chapters provide theoretical and applied perspectives, and consider Indigenous and other threatened languages from various regions of the world including the Americas, Australia, Europe, the Indian subcontinent, and Southeast Asia. This volume is the first in the FEL Yearbook Series.
